80's A998/A999 into Early A

The adapter bushing makes the hub register in a later model crank smaller so it captures the earlier torque converter snout.
Why some have trouble understanding a bushing makes a hole smaller, not larger, is a mystery to me.
The 998 and 999 are lock up type, but not overdrive. If the custom built convertor isn't the lock up type, this swap is a waste of time.
